Studies On Adding Storey To Reform Of Jacket Frame

Adding storey to reform the building not only economized the building site, but decrease the price of construction. It is an attractive work. Adopting which reforming-project will be an important problem, because it is related to the possibility, safety and economic of the project. No enough attention will result in not agreeing with the anti-earthquake request, leave new danger to buildings, and change the building into "Dangerous building" . So it is very necessary to research the best structure for storey in a building.This paper have been different structure form increasing storey discussed by analyzing the applying of Jacket frame in the earthquake and introducing some examples of the different regions. Through researching practical engineering on anti-earthquake analysis between the concrete structure and storey-between truss, this paper compared dynamic period and seismic behavior of this two kinds of structures, calculated force and deflection, put forward into the storey-between truss is an economic, reasonable, practical structure, it can conveniently construct and save space.The essay just is initial study about adding storey, it must have some imperfect points, leaving further study in the practice.
